Websites that need to meet Section 508 Accessibility Rules and other government agency accessibility guidelines are tasked with the requirement to label links to downloadable content with the file type and file size of the referenced media, like PDFs. This creates the task of maintaining countless links entered into the body content of pages across the entire website. This task is nearly impossible to perform manually, considering that these links may reference external content on other websites not controlled by the content manager. So, when a PDF file is updated at the same URL the file size needs to be recalculated or else the download link label is no longer meeting regulations. Will all of these other website's have the courtesy of notifying the content manager when the file size changes for a PDF that they host?
